Embodiment

In existing LTE-TDD, due to using identical frame structure between the network equipment and all terminals, therefore flexibly The configuration of subframe and its attribute (upstream or downstream) are also consistent.And in embodiments herein, the network equipment is using complete Duplex, terminal are used in semiduplex communication pattern, and the network equipment can be according to the needs of each terminal or the network equipment Need independent adjustment frame structure, that is to say, that the different terminals of consolidated network device service can use each different frame knots Structure.Because uplink and downlink are defeated using keeping pouring in together, therefore the design of frame structure may be referred to LTE-TDD pattern.Net above Network equipment can be base station, or have other network side equipments of base station similar functions.

In view of the needs of terminal initial access, the frame structure of an acquiescence is can specify that, the frame structure is set without network Held consultation between standby notice terminal or the network equipment and terminal.Under the frame structure of the acquiescence, the network equipment uses in advance about The time slot set and cycle send synchronizing signal, being initially accessed of receiving terminal to terminal, capability negotiation is carried out with terminal or Ability confirmation etc. is carried out with terminal, it is ensured that new terminal can be by this in the case where passing through negotiation not between the network equipment The frame structure of acquiescence accesses at any time, and the frame structure of acquiescence can be frame structure as defined in existing LTE-TDD or newly determine Justice, by taking Fig. 2 as an example, the frame structure of acquiescence can be frame structure corresponding to any one index value in Fig. 2, and the length of wherein frame can With (it is of course also possible to redefining new frame length as needed) identical with the length of frame in LTE-TDD, i.e., wrapped in each frame Include 10 subframes.N kind frame structures are shared in Fig. 2, maximum frame structure index value is n-1.To be existing corresponding to index value 0~6 The existing frame structures of LTE-TDD, be the following n-7 kind frame structures that may be increased newly corresponding to index value 7~(n-1), frame structure x and X+1 represents any two kinds of adjacent frame structures in this n-1 kind frame structure.It should be noted that n is not necessarily required to be more than 6, i.e., not Necessarily need all to adopt frame structure all in existing LTE-TDD in the lump, especially, n can also be 1, i.e., only provide a kind of Frame structure and by its frame structure by default.Preferably, in order to which terminal is preferably synchronous, in the subframe that synchronizing signal is sent, All it is configured to descending, such as synchronizing signal can be sent in the 0th subframe and the 5th sub-frame configuration.Without loss of generality, it is assumed that frame structure x Frame structure for acquiescence and only send synchronous letter in #0 (wherein # represents that order, such as #0 represent No. 0, i.e., the 0th) subframe Number, then new terminal only sends access request in the #2 subframes of each frame, and the network equipment and terminal can carry out ability after access Negotiation or requirement negotiation, the sub-frame property being confirmed whether in frame structure to be adjusted.So through consultation, the network equipment can be thought Sub-frame property in the independent adjustment frame structure of each terminal so that each terminal can be adjusted to each suitable frame knot Structure, systematic function can be obviously improved.Then the network equipment and terminal can are entered according to the frame structure after adjustment sub-frame property Row communication.

Specifically, full duplex is used in the network equipment, terminal is used in semiduplex communication pattern, and the network equipment covers at it The current frame structure of any terminal is unsatisfactory for the terminal or when needing of the network equipment in the range of lid, can be to the present frame Sub-frame property in structure is modified, and the information that sub-frame property is changed temporarily is notified to the terminal, the sub-frame property The information changed temporarily includes being used to indicate the terminal by least one subframe in the current frame structure by up son Frame is changed to descending sub frame, or an at least subframe is changed to the information of sub-frame of uplink by descending sub frame.The network equipment can be with It is independently adjustable the sub-frame property of change different terminals.Here current frame structure can be acquiescence frame structure or The frame structure updated after sub-frame property change.The information changed temporarily of sub-frame property of network equipment transmission is received in terminal Afterwards, the network equipment and terminal communicate according to the frame structure after the sub-frame property is changed is changed.

The needs that current frame structure is unsatisfactory for the network equipment mainly include：The load of the network equipment changes.Currently Frame structure be unsatisfactory for the needs of terminal and mainly include：The business of terminal, the position of terminal, the disturbed condition of terminal and terminal One or more parameter in channel quality changes.Certainly, it is not to say that these parameters need to adjust once changing The attribute of whole change subframe, the change for simply saying these parameters are the premises for the sub-frame property changed in terminal frame structure.

Illustrated below so that the business of terminal changes as an example.

Scene one：When terminal A uses the frame structure x progress network browsing operations in Fig. 2, terminal B request is connected to, it is desirable to One file of transmission gives terminal B, because the sub-frame of uplink in frame structure x is less, so transmission can not be rapidly completed, in order to as early as possible Uplink is completed, the network equipment may decide that and temporarily change some descending sub frames in frame structure x currently used terminal A For sub-frame of uplink.Due to the network equipment it is known that the size of this document, so this subframe more can also be predicted accurately Attribute changes duration temporarily.Similarly, if terminal A according to frame structure 0 when uploading document, be connected to terminal B please Ask, it is necessary to receive a file from terminal B theres, then the network equipment can also be by frame structure 0 currently used terminal A Some sub-frame of uplink are changed to descending sub frame, can so accelerate to receive the speed of file from terminal B, similarly, due to knowing The size of this document, it more can accurately predict this duration changed temporarily.

Scene two：Terminal A and terminal B use the frame structure 1 in Fig. 2 to carry out video conversation, and terminal B temporary needs is to terminal A transmits a file, at this time, in order to accelerate the transmission of this document, for terminal A, it is necessary to by some in frame structure 1 Row subframe is changed to descending sub frame, and, it is necessary to which some descending sub frames of frame structure 1 are changed into sub-frame of uplink for terminal B.

The change temporarily of this sub-frame property can actively be initiated by the network equipment, can also actively be initiated by terminal.Due to The network equipment possesses more information and inherently has scheduling feature, therefore, initiates sub-frame property by the network equipment and changes temporarily Can advantageously.Illustrated below so that the network equipment initiates sub-frame property change temporarily as an example.

As shown in figure 3, any terminal that terminal 12 in Fig. 3 services for the network equipment 11 (attention is any terminal here, The different terminals of network device services can be done with each independent processing), in step 301, the network equipment 11 and terminal 12 Communicated using frame structure i (0≤i≤n-1), subframe category is changed temporarily in the needs similar to above-mentioned scene one and scene two Property situation in, the network equipment 11 step 302 determine will to current frame structure at least one subframe sub-frame property carry out Interim modification, and the information in step 303 changing sub-frame property temporarily is notified to terminal 12, notice terminal 12 need according to The sub-frame property of a subframe in a certain frame for the information change frame structure i that interim sub-frame property is changed temporarily, for example, by frame Original a certain descending sub frame is changed to sub-frame of uplink in structure i a certain frame, or by frame structure i a certain frame it is original certain One sub-frame of uplink is changed to descending sub frame.Terminal 12 receive after above- mentioned information according to the information that above-mentioned sub-frame property is changed temporarily after Step 304 is modified to frame structure i, and in step 305, terminal 12 is led to using the frame structure after change with the network equipment Letter.Alternatively, the network equipment 11 and terminal 12 can arrange the duration changed temporarily or the network equipment 11 in advance in step The duration is informed into terminal 12 in the lump in rapid 303, then the frame structure of terminal 12 reverts to original after terminating in the duration The frame structure i come, the network equipment 11 and terminal 12 communicate by frame structure i again, because this step is optional, therefore step in Fig. 3 306 ' it is dotted line to recover original frame structure i '.

The information that above-mentioned sub-frame property is changed temporarily can be an independent signaling, can also be included in the things such as PDCCH Manage in control channel, RRC (Chinese full name can also be included in：Radio resource control layer；English full name：Radio Resource Control) in signaling, in addition can also in the case of the network equipment with terminal treaty rule by it is non-it is explicit in a manner of transmit.

It is above-mentioned to be illustrated by taking the network equipment as an example, but in D2D communications, it may be possible to the terminal as emitter The role of the network equipment is undertaken, for ease of understanding, is described below by taking the network equipment as an example.But those skilled in the art Member is it should be understood that the step of network equipment performs in embodiment in the application is equally applicable in D2D communications as emitter Terminal.

Also have in addition a little it is noted that the special subframe in tdd frame structure is because terminal is needed from downlink reception shape State is converted to one section of GP (English full name that up transmission state needs the time and inserted in the burst：Guard Interval； Chinese full name：Protection interval), i.e. next subframe of special subframe is sub-frame of uplink certainly.Once sub-frame property is become Change, then the position (namely GP position) of special subframe be able to may also change, i.e., original special subframe can basis The interim change directive of sub-frame property is changed into sub-frame of uplink, or, if if the subframe closelyed follow is more after original special subframe It is changed to descending sub frame, then It is not necessary to set GP in the special subframe, therefore be also correspondingly changed to common descending Subframe.And in the frame structure after change sub-frame property temporarily, as long as the previous subframe of sub-frame of uplink is descending sub frame, then should Just need to set GP in descending sub frame, i.e. the descending sub frame just needs to be changed to special subframe.Accordingly it is also possible to be understood that, Although the interim change directive of sub-frame property may simply specify the son of the attribute, actually Alternative Attribute that have changed a subframe Frame may more than one.

In addition, the network equipment can also modify as terminal to the sub-frame property in the terminal current frame structure, net Network equipment is after making the decision-making to the interim change of sub-frame property and sending the information that the sub-frame property is changed temporarily, equally To carry out the frame structure after sub-frame property change temporarily according to the terminal to communicate with terminal, this principle is also applied for following reality Apply example.The specific time of general recommendations network equipment modification sub-frame property and terminal are synchronous.

Especially, the time that sub-frame property changes starting temporarily can also be included in the information that sub-frame property is changed temporarily, The attribute for the subframe that the information that the network equipment and terminal are changed temporarily according to the time change sub-frame property of the starting is specified, but Generally all it is that the frame where the information changed of the sub-frame property is sent temporarily is just changed accordingly, below with the network equipment The frame where the information that the sub-frame property is changed temporarily is just changed and carried out with the frame structure after renewal accordingly with terminal Illustrate exemplified by communication.

Individually sent in addition, the information that sub-frame property is changed is the terminal serviced by the network equipment it temporarily, such as Fruit is that one group of terminal (and not all terminal) that the network equipment is serviced it is uniformly modified, then sub-frame property is changed temporarily In information can include instruction terminal group information or by corresponding to this group of terminal on common source transmission represent this be Change to the unified sub-frame property carried out of this group of terminal, change the side that method and principle change sub-frame property with a terminal Method is consistent with principle, therefore still illustrates below by taking a terminal as an example.

Illustrate to change the attribute of subframe in current frame structure how temporarily below by different embodiments.

Embodiment one：

The network equipment determines that current frame structure is unsatisfactory for terminal or when needing of the network equipment, the network equipment The information that sub-frame property is changed temporarily notified to the terminal, for example, the network equipment is in the subframe #t of a radio frames, (t is Integer) to terminal the information changed temporarily of sub-frame property is sent, the information that the sub-frame property is changed temporarily is included for indicating Subframe #t+k (k is positive integer) in the radio frames is changed to descending sub frame or by descending son by the terminal by sub-frame of uplink Frame is changed to the information of sub-frame of uplink.Terminal is received after the information that the sub-frame property is changed temporarily to the son in current frame structure Frame Properties adjusts accordingly.The information that above-mentioned sub-frame property is changed temporarily can also be changed lasting temporarily including sub-frame property The number of sub frames k of the skew of time (generally being represented with frame number m, m is positive integer) and/or subframe to be changed and present sub-frame.On It can also be that the network equipment and terminal are appointed and are stored in the network equipment and terminal in advance to state m and k.For example, network is set M has been prestored in standby and terminal, when the information that network equipment transmission sub-frame property is changed is to terminal temporarily, the sub-frame property In the information changed temporarily and the value of the m need not be included.Terminal receives the information that the sub-frame property is changed temporarily after, according to it The m of storage it is known that, this time sub-frame property changes duration temporarily.

The subframe for needing to change temporarily is quickly found in order to facilitate the network equipment and terminal, above-mentioned k can also be set by network Standby and terminal is made an appointment, for example, can prestore the index value and subframe of a frame structure in the network equipment and terminal Offset the contrast relationship table between k (k is positive integer).For example, the contrast relationship table can be as shown in Fig. 2 each frame knot Structure corresponds to one and up changes descending sub-frame offset k values and one descending changes up sub-frame offset k values, sub-frame offset k values Corresponded with the index value of frame structure/frame structure.

Certainly, it should be pointed out that the numeral in form is only to illustrate, and may further specify that each frame structure pair in Fig. 2 The two k values answered are consistent.It may further specify that the corresponding identical k value of all frame structures, such as by k corresponding to all frame structures Value be both configured to 3, or all frame structures share identical k value, and this k value can be with dynamic change, at this moment The network equipment needs that the k values after dynamic change are broadcast into all terminals by other signalings, repeats no more here.

Because the information that all sub-frame properties are changed is sent by descending sub frame temporarily, therefore k value takes into account son The conveniency and neighbouring change principle that the information that Frame Properties is changed temporarily is understood.By Fig. 2, it can be seen that, k value does not take 1, original Because being that usual terminal is just to start decoding detection to the subframe after complete subframe is received, for example, the network equipment is descending Subframe t sends the information that sub-frame property is changed temporarily after, terminal just starts to carry out subframe t in the time corresponding to subframe t+1 Decoding detection, so if k is taken as 1, then terminal has had little time react.For giving a concrete illustration, for frame Structure 1, the information that the network equipment is changed temporarily in subframe #4 transmission sub-frame properties, if k=1, terminal is needed subframe #5 Sub-frame of uplink is changed to by descending sub frame, and in subframe #5, because terminal is also carrying out subframe #4 decoding detection, therefore not yet obtain Taking the information that sub-frame property is changed temporarily, i.e., terminal, which has no knowledge about subframe #5, needs to be changed to sub-frame of uplink by descending sub frame, therefore, Terminal is also carrying out subframe #5 reception downstream signals, and so there have been disorder.Certainly, alternatively, can also be pre- First prescribed terminal begun to after signal corresponding to control channel has been received first to control channel decode, so that k=1 also into In order to possible, but also improve the requirement to terminal.K value can also dynamically update in above-mentioned Fig. 2, at this moment need the network equipment The value of the k after dynamic change is broadcast to all terminals by other signalings.Or k value may be also configured to and industry Service type corresponds.

Another question is that this sub-frame property is changed needs and lasted long temporarily, usually, can specify that The change temporarily of this sub-frame property needs to continue m frames, recover original frame structure after m frames or the network equipment resend it is new The message that sub-frame property is changed temporarily, m value can be prespecified as k values, or even also can also be according to different frame knots Structure takes different values, is preserved simultaneously in the network equipment and terminal.M value can also determine temporarily according to current traffic situation, than As in scene two due to knowing file size to be passed, so the network equipment can be according to file size to be passed and the system of present channel Meter situation estimates m value, and it is notified to terminal.

Either k value or m value just notify terminal can be determined by the network equipment temporarily after, such as in subframe category Increase the domain for indicating k values and/or the domain for indicating m values in the information that property is changed temporarily.This mode is more flexible, example In frame structure 0, the information that the network equipment is changed temporarily by sub-frame property in #0 subframes clearly informs terminal k=2, then Mean that this change needs to change subframe #2 (t=0, k=2, therefore t+k=2) attribute, and subframe #2 was up son originally Frame, it is therefore desirable to subframe #2 is changed to descending sub frame by sub-frame of uplink, meanwhile, as it was previously stated, the position of special subframe is possible to Needing to change, in this example, former special subframe #1 subframes are changed to common descending sub frame, and because #3 is sub-frame of uplink, therefore #2 Subframe is special subframe.

Specific implementation when, can not also prespecified sub-frame property temporarily change need duration, for example, not advising Fixed above-mentioned m value, but a signaling is sent when the network equipment judges to think that this terminates this interim change, inform end The frame structure before change is recovered at end, and also or the information changed temporarily by new sub-frame property of the network equipment informs that terminal is recovered Frame structure before change.Illustrated below exemplified by m value is prestored in the network equipment and terminal.

The present embodiment discusses k values and frame structure index value one-to-one corresponding and changeless situation by taking Fig. 2 as an example, but It is also applied for other various situations.Before sub-frame property change temporarily is initiated, the network equipment and terminal are all preserved and are similar to Form shown in Fig. 2.

In similar to above-mentioned scene one and scene two, the network equipment detects that the current frame structure of terminal is not suitable for terminal Or when needing of the network equipment, such as the network equipment detects the loading of the network equipment, the business of the terminal, the terminal Position, the disturbed condition (including interference by other-end and/or disturb other-end) of the terminal and described One or more parameter in the channel quality of terminal changes, and the network equipment sends a sub-frame property to terminal and faced Shi Genggai information, the information carried in this information include but is not limited to：Descending sub frame (is changed to up by up-downgoing change direction Subframe, or sub-frame of uplink is changed to descending sub frame), i.e., descending sub frame is changed to sub-frame of uplink or by up son for instruction terminal Frame is changed to descending sub frame.If the network equipment and terminal do not preserve Fig. 2 or the k values of needs are different from the k values in Fig. 2, K value can also be included in the information that sub-frame property is changed temporarily, wherein k is to need to change the subframe of sub-frame property and current son Frame #t skew number of sub frames.If it is different from the m values preserved that the network equipment and terminal do not preserve m value or the m values of needs, M value can also be included in the information that then sub-frame property is changed temporarily, wherein m is the frame number for maintaining described interim change.

The information that the sub-frame property that terminal receives network equipment transmission is changed temporarily after, according to the k values received or eventually Hold the contrast relationship table (such as Fig. 2) between index value and sub-frame offset k according to frame structure/frame structure of preservation to find terminal to work as K values corresponding to the preceding frame structure used, and change the t+k subframe of each frame since the continuous m frame present frame Sub-frame property.If the t+k subframe for sub-frame of uplink, the t+k subframe is changed to descending sub frame, if t+ K subframe for descending sub frame, then the t+k subframe is changed to sub-frame of uplink.

For example, the current frame structure of terminal is frame structure 0, as shown in figure 4,

The value for the k that terminal prestores with the network equipment is 4 (see Fig. 2), then terminal receives network equipment hair in #0 subframes The sub-frame property of #4 subframes is changed to descending sub frame by sub-frame of uplink the information that the sub-frame property sent is changed temporarily after, after change Frame structure 0 shows that this is the subframe that have changed attribute as shown in figure 5, being underlined in figure with oblique black matrix, to compare, before change Frame structure 0 be also placed in the lump in table, also do same processing below.

Network equipment side is also required to for the frame structure to communicate with the terminal to be changed to the frame structure shown in Fig. 5.Then, terminal Communicated between the network equipment using the frame structure 0 after the change shown in Fig. 5, until m+1 frames, terminal and the network equipment Frame structure is changed to the frame structure 0 (as shown in Figure 4) of original (before changing) again.Subsequent terminal and the network equipment, which use, to be pressed Original frame structure 0 shown in Fig. 4 is communicated.

Above-described embodiment illustrates by taking frame structure 0 as an example, and in actual applications, other frame structures can also use Similar method.It is that the attribute of subframe is changed to descending sub frame by sub-frame of uplink, in practical application in addition, in above-mentioned example In, sub-frame property can also be changed to sub-frame of uplink by descending sub frame, because method is similar, here is omitted.

As it was previously stated, the conversion between downstream-to-upstream for convenience, every kind of frame structure is from descending sub frame to up son A special subframe is all provided between frame, therefore, when changing frame structure, it is also contemplated that it is this change whether can influence it is descending To the conversion between up.For example, when the network equipment by the information instruction terminal that sub-frame property is changed temporarily by present frame knot #t+k subframes in structure from descending sub frame be changed to sub-frame of uplink when, terminal and the network equipment are in the same of change #t+k sub-frame properties When, it is also contemplated that #t+k-1 subframes, if #t+k-1 subframes are descending sub frames, set #t+k-1 subframes as special subframe.

When temporarily the information instruction terminal that the network equipment is changed by sub-frame property is by the #t+k subframes in current frame structure When being changed to descending sub frame from sub-frame of uplink, if #t+k-1 subframes are special subframe, the network equipment and terminal are also needed to #t+k- 1 subframe is changed to common descending sub frame.Further, if #t+k+1 subframes are sub-frame of uplink, the network equipment and terminal are not #t+k subframes can be changed to descending sub frame, but #t+k subframes are changed to special subframe.

In example as shown in Figure 5 above, because #3 subframes are sub-frame of uplink, therefore special subframe need not be changed to, And #5 subframes are descending sub frame, therefore #4 subframes are without being further changed to special subframe.

But as shown in fig. 6, according to Fig. 2, k corresponding to frame structure 6 is 2, then send sub-frame property in #0 subframes changes temporarily Information sub-frame of uplink is changed to descending sub frame, corresponding #2 subframes are revised as descending sub frame, because #1 subframes are in former frame structure Special subframe and #3 subframes are sub-frame of uplink, so need #1 being changed to generic downlink subframe, and #2 subframes will be changed further For special subframe.

Terminal can be partly or entirely sent in a manner of implicit in the information that sub-frame property is changed temporarily.For example, K and m value is predefined, all pre-saves the similar Fig. 2 table of comparisons with terminal both sides in the network equipment.Direction is changed in up-downgoing Information similarly can be by the way of implicit, and it is the network equipment that the premise of this mode, which is the existing assignment to sub-frame of uplink, Sent in prespecified descending sub frame.Or by taking frame structure 0 as an example, it is assumed that sub-frame of uplink #2, #3, #4 assignment message are all Sent in subframe #0, sub-frame of uplink #7, #8, #9 assignment message are all sent in subframe #5 (to be only to illustrate here, specifically refer to Can be according to being actually needed flexible change with form).So, when the network equipment needs instruction terminal will be upper in current frame structure When row subframe is changed to descending sub frame, the network equipment does not send or lacked in the descending sub frame #t that script should carry out up assignment One or more up assignation informations for being directed to the terminal are sent, correspondingly, it is read as needing by terminal after receiving subframe #t The attribute of one or more subframes is changed, up-downgoing change directional information is to be changed to descending sub frame by sub-frame of uplink.Such as if eventually End only receives 2 up assignments by frame structure 0 in #0 subframes, and should receive 3 up assignments according to default frame structure 0, 1 assignment is received less, then is now then adjusted frame structure 0 by Fig. 5 according to Fig. 2, k=4.

Similarly, when the network equipment needs instruction terminal that descending sub frame is changed into sub-frame of uplink, the network equipment is in original This should not carry out occurring up assignment message in the descending sub frame #t of up assignment or should be carried out in original under up assignment There are more up assignment messages in row subframe, then correspondingly, it is also read as needing the son for changing #t+k subframes by terminal Frame Properties, up-downgoing change directional information is to be changed to sub-frame of uplink by descending sub frame.Such as or by taking frame structure 0 as an example, it is assumed that Sub-frame of uplink #2, #3, #4 assignment message are all sent in subframe #0, and sub-frame of uplink #7, #8, #9 assignment message are all in subframe #5 Send, if terminal receives up assignment in the #1 subframes of frame structure 0, and according to normal flow, #1 of the terminal in frame structure 0 It is that receive up assignment in subframe, i.e., to receive 1 up assignment, thus terminal knows needs to current frame knot more Subframe in structure is adjusted, for example, terminal then can be adjusted frame structure 0 by Fig. 7, it can be seen that eventually according to Fig. 2, k=5 End not only have adjusted #6 sub-frame property by Fig. 2 k=5 indicated, and because #5 is descending sub frame, therefore #5 is also required to accordingly Ground is adjusted to special subframe.Certainly, the mode of this adjustment change in the network equipment and terminal is synchronous, i.e. the network equipment Corresponding adjustment change can be done.

It is pointed out that either k value or m value just notify eventually can also be determined by the network equipment temporarily after End, for example increase the domain for indicating k values and/or the domain for indicating m values in the information that sub-frame property is changed temporarily.It is this Mode is more flexible, such as in frame structure 0, in the information that the sub-frame property of network equipment transmission is changed in #0 subframes temporarily K=2 is clearly specified, and subframe #2 is sub-frame of uplink, then means that this change is that #2 is changed into descending sub frame by sub-frame of uplink, And #1 subframes are changed to common descending sub frame, and because #3 is sub-frame of uplink, therefore #2 subframes are special subframe, as shown in Figure 8.

Embodiment two

The information that the difference of the present embodiment and embodiment one is changed temporarily in the sub-frame property in embodiment one The attribute of a subframe is changed for instruction terminal, and the information that the sub-frame property in the present embodiment is changed temporarily can be used for referring to Show the attribute of the multiple subframes of terminal modifications.

The network equipment determines that current frame structure is unsatisfactory for terminal or when needing of the network equipment, and sub-frame property is faced Shi Genggai information notifies to change the attribute of multiple subframes to the terminal, instruction terminal.For example, the network equipment is wireless at one The information that t-th of subframe of frame is changed temporarily to terminal transmission sub-frame property, the information that the sub-frame property is changed temporarily include For indicating the terminal by the individual subframe (for example, the t+k subframe to the t+k+L-1 subframe) in the radio frames Sub-frame of uplink is changed to descending sub frame or descending sub frame is changed to the information of sub-frame of uplink, and wherein t is whole more than or equal to zero Number, k and L are positive integer.

The sending method for the information that above-mentioned sub-frame property is changed temporarily can use the TTI being similar in existing LTE system (Chinese full name：Transmission time interval；English full name：Transmission Time Interval) binding mode.For example, Descending sub frame #t (0≤t≤9), the network equipment send the TTI binding assignment message of terminal in PDCCH, and terminal is according to prior rule Fixed sequential, in #t+k, #t+k+1 ..., #t+k+L-1 subframes uniformly carry out downlink reception or uploaded to send.

When TTI binding is up assignment, terminal and the network equipment are to the sub-frame of uplink in this L subframe under frame structure i Do not change, and descending sub frame therein is changed to sub-frame of uplink.If #t+k-1 subframes are descending sub frames, the network equipment and Terminal also needs to #t+k-1 subframes being set as special subframe.

Or when TTI binding is descending assignment, terminal and the network equipment are to descending in this L subframe under frame structure i Subframe is not changed, and sub-frame of uplink therein is changed into descending sub frame.If #t+k-1 subframes are special subframes, network is set Standby and terminal also needs to #t+k-1 subframes being changed to descending sub frame.If #t+k+L is sub-frame of uplink, stands and terminal is also needed to # T+k+L-1 subframes will be set to special subframe.

After frame structure communication a period of time (for example, m radio frames) after change, the network equipment and terminal are by frame knot Structure reverts to the frame structure i before change.

Similar with embodiment one, the value of one or more parameters can in advance provide and be stored in the network equipment in m, k and L In terminal, by signaling to terminal can also be determined by the network equipment temporarily after.For needing to notify the ginseng to terminal Number, can be placed it in the information that sub-frame property is changed temporarily.Especially, k even can elect 0 as here, because During descending binding assignment, the PDCCH of #t subframes can bind descending L subframe of the instruction since #t subframes.

For example, still by taking frame structure 0 as an example, it is assumed that the network equipment and terminal all pre-save k and l information, k=3, L=3, when the network equipment network equipment determines that current frame structure is unsatisfactory for terminal or when needing of the network equipment, in son Frame #0 sends TTI binding assignment message to terminal, and it is sub-frame of uplink that subframe #3, #4, #5 are assigned in a manner of TTI binding, terminal After receiving TTI binding assignment message, subframe #5 is changed to sub-frame of uplink, frame structure is just adjusted to Fig. 9.

In order to ensure smoothly to communicate with terminal, when terminal is communicated using the frame structure after change with the network equipment, The network equipment is also required to communicate with terminal according to the frame structure after change.

It is that the attribute of subframe is changed to sub-frame of uplink by descending sub frame in above-mentioned example, in actual applications, can also Sub-frame property is changed to descending sub frame by sub-frame of uplink, method is similar.It should be noted that if #t+k-1 subframes are special son Frame, then terminal and the network equipment also need to #t+k-1 subframes being changed to descending sub frame, if #t+k+L subframes are sub-frame of uplink, eventually End and the network equipment also need to #t+k+L-1 subframes being set to special subframe, and here is omitted.

Embodiment three

The present embodiment provides the mode that sub-frame property is changed in a kind of position using special subframe temporarily.Assuming that the network equipment When needing of terminal is unsatisfactory in the frame structure of terminal, is sent to the information that one sub-frame property of terminal is changed temporarily, the subframe The information that attribute is changed temporarily includes：Up-downgoing change directional information, the number of sub-frames Q for needing interim change sub-frame property.Should The information that sub-frame property is changed temporarily can further include the duration for maintaining this to change temporarily (generally with frame number m tables Show, m value can also be determined temporarily with prespecified, recover original frame structure after m frames or the network equipment is resend The message that new sub-frame property is changed temporarily).Terminal is received after the information that the sub-frame property is changed temporarily in current frame structure The sub-frame property of part subframe is modified.

Up-downgoing change directional information can serve to indicate that Q sub-frame of uplink in current frame structure is changed to down by terminal Row subframe, it can be used for instruction terminal and Q descending sub frame in current frame structure be changed to sub-frame of uplink.For convenience of reader Understand, both of these case will be illustrated by specific example below：

1) up-downgoing change directional information can serve to indicate that terminal by Q sub-frame of uplink in the current frame structure more It is changed to descending sub frame：

The information that the network equipment is changed temporarily in the subframe #t transmission sub-frame properties of a radio frames, the sub-frame property are interim The information of change includes up-downgoing change directional information and Q values.Terminal is adjusted receive the information that sub-frame property is changed temporarily after Whole frame structure, for example, terminal finds first special subframe #s after subframe #t in current frame structure, then in order should Special subframe #s and the 1st to the Q sub-frame of uplink afterwards are changed to descending sub frame.If subframe #s+Q+1 is sub-frame of uplink, Subframe #s+Q is further changed to special subframe by terminal.

Or by taking frame structure 0 as an example temporarily, it is assumed that the information that the network equipment is changed in #0 subframes transmission sub-frame property, the son The information that Frame Properties is changed temporarily includes up-downgoing change directional information and Q values, wherein, up-downgoing change directional information is used for Sub-frame of uplink is changed to descending sub frame, Q=2 by instruction terminal.Terminal is received after the information that the sub-frame property is changed temporarily to current The frame structure 0 used is adjusted, and the frame structure 0 after adjustment is as shown in Figure 10, and first special subframe after #0 subframes is son Frame #1, in addition, as it was previously stated, in order to allow terminal to be successfully converted to up transmission state, it is necessary to adjust by downlink receiving state Whole GP position, therefore special subframe #1 is changed to common descending sub frame and descending sub frame will be changed to by Q sub-frame of uplink thereafter, Descending sub frame is changed to due to Q=2, therefore by subframe #2 (the 1st) and subframe #3 (Q=2), simultaneously as subframe #4 For sub-frame of uplink, subframe #3 will be changed to special subframe.Network equipment side is also required to do frame structure and adjusted with terminal identical. The network equipment is communicated after the information changed of the sub-frame property is sent temporarily according to the frame structure after renewal, correspondingly, Terminal is communicated after the information changed of the sub-frame property is received temporarily according to the frame structure after renewal.If subframe is interim Change duration is m frames, then the network equipment and terminal revert to original frame structure (before changing in m+1 frames Frame structure).

In addition to this mode above, terminal and the network equipment can also use another mode will be current according to Q values Q sub-frame of uplink in frame structure is changed to descending sub frame and does not change the position of special subframe, i.e., according to after special subframe One descending sub frame is counter forward to push away Q subframe, i.e. inverted sequence.Or with the example of Q=2 in above-mentioned frame structure 0, after special subframe #1 First descending sub frame is subframe #5, then need to only change the attribute of 2 subframes (subframe #3 and subframe #4) before subframe #5, change Frame structure 0 such as Figure 11 afterwards.Because principle is similar, therefore repeat no more.

2) up-downgoing change directional information can serve to indicate that terminal by Q descending sub frame in the current frame structure more It is changed to sub-frame of uplink：

The information that the network equipment is changed temporarily in the subframe #t transmission sub-frame properties of a radio frames, the sub-frame property are interim The information of change includes up-downgoing change directional information and Q values, and directional information is changed in the up-downgoing will for instruction terminal Descending sub frame is changed to sub-frame of uplink.Terminal adjusts frame structure receive the information that sub-frame property is changed temporarily after, for example, terminal is looked for First special subframe S into current frame structure after subframe #t, then by the 1st after special subframe S to Q Descending sub frame is changed to sub-frame of uplink.

Or by taking frame structure 0 as an example temporarily, it is assumed that the information that the network equipment is changed in #0 subframes transmission sub-frame property, the son The information that Frame Properties is changed temporarily includes up-downgoing change directional information and Q values, wherein, up-downgoing change directional information is used for Descending sub frame is changed to sub-frame of uplink by instruction terminal, Q=1 in this example.Terminal receives the information that the sub-frame property is changed temporarily Current frame structure 0 is adjusted afterwards, frame structure such as Figure 12 corresponding to the frame structure 0 after adjustment, first after #0 subframes Special subframe is subframe #1, and according to aforementioned rule, first descending sub frame #5 is changed to sub-frame of uplink after special subframe #1, due to Descending sub frame switches to the position of sub-frame of uplink not change, therefore special subframe position here does not change.Network Equipment side is also required to do frame structure and adjusted with terminal identical.The network equipment is sending the information changed temporarily of the sub-frame property Communicated afterwards according to the frame structure after change, correspondingly, terminal after the information changed of the sub-frame property is received temporarily i.e. Communicated according to the frame structure after change.It is m frames that if subframe changes duration temporarily, then the network equipment and terminal The until m+1 frames revert to original frame structure (frame structure before changing).

In another embodiment, the information that above-mentioned sub-frame property is changed temporarily can also by it is non-it is explicit in a manner of pass Send, i.e., the network equipment does not have to the information that the sub-frame property is changed temporarily is sent into terminal by message.Sub-frame property is interim more Up-downgoing in the information changed changes directional information and needs the number of sub-frames (for example, Q value) for changing sub-frame property can Terminal is notified by non-explicit mode.If it is related to duration (such as lasting the frame number m), m of sub-frame property change Value need to appoint and be stored in the network equipment and terminal in advance.

For example for, when the network equipment determines that current frame structure is unsatisfactory for the needs of terminal or the network equipment When do not send in the descending sub frame #t that script should carry out up assignment or send less the up assignation informations of the Q terminals. It is read as needing the Q sub-frame of uplink by after first special subframe #s after subframe #t by terminal after receiving subframe #t Attribute changes be descending sub frame, or as in the prior embodiments by after first special subframe #s after subframe #t The attribute changes of Q sub-frame of uplink are descending sub frame before first descending sub frame.For example the currently used frame structure of terminal is Frame structure 0 in Fig. 2, if the network equipment determines that frame structure 0 is unsatisfactory for the needs of terminal, the network equipment can be to frame structure 0 Sub-frame property in corresponding frame structure is modified, for example, the network equipment can be according to Figure 10 or Figure 11 frame structure 0 The attribute of corresponding subframe is changed so as to update frame structure.It is assumed that the sub-frame of uplink #2 in frame structure 0, #3, #4 assignment message are all Sent in subframe #0, subframe #7, #8, #9 assignment message are all sent in subframe #5, for the letter for changing sub-frame property temporarily Breath notice can only send 1 up assignment to terminal, the network equipment in #0 subframes, that is, lack Q=2 up assignments.Terminal A up assignment is only received in #0 subframes, by taking Figure 10 as an example, terminal is needed subframe #2 and subframe #3 attribute according to Q=2 It is changed to from sub-frame of uplink descending, terminal determines whether that then subframe #3 is special subframe because subframe #4 is sub-frame of uplink, That is, frame structure is have updated in the way of Figure 10.

When the network equipment according to terminal or the network equipment it needs to be determined that needing the descending son in current frame structure When frame is changed to sub-frame of uplink, the network equipment sends the information that sub-frame property is changed temporarily and changed temporarily to terminal, the sub-frame property Information in up-downgoing change directional information descending sub frame is changed to sub-frame of uplink, and the network equipment for instruction terminal Occur Q up assignment messages in the descending sub frame #t that should not carry out up assignment originally or should carry out up finger in original There are Q up assignment messages in the descending sub frame matched somebody with somebody.It is read as after needing to change subframe #t by terminal after receiving subframe #t Descending sub frame, i.e., be changed to sub-frame of uplink by the attribute of the descending sub frame after first special subframe.For example terminal is currently used Frame structure is the frame structure 0 in Fig. 2, if the network equipment determines that frame structure 0 is unsatisfactory for the needs of terminal, the network equipment can be right Sub-frame property in frame structure 0 is modified, for example, the network equipment can change corresponding subframe according to Figure 12 frame structure 0 Attribute.It is assumed that in frame structure 0, sub-frame of uplink #2, #3, #4 assignment message are all sent in subframe #0, sub-frame of uplink #7, #8, # 9 assignment message is all sent in subframe #5, and in order to which the information for changing sub-frame property temporarily is notified to terminal, the network equipment can be with 4 up assignments are sent in #0 subframes, i.e., the more individual up assignments of Q=1, terminals have received 4 up assignments in #0 subframes, i.e., More a up assignment, terminals then know that subframe #5 attribute is changed to sub-frame of uplink by needs according to Q=1 from descending sub frame, Namely update frame structure in the way of Figure 12.

No matter up-downgoing change directional information is indicated for terminal is changed to descending sub frame or for referring to by sub-frame of uplink Show that descending sub frame is changed to sub-frame of uplink by terminal, these Q values implied before special subframe in each descending assignment can add up, Such as in frame structure 1, if the network equipment is finding to need the sub-frame property (either any change) for changing two subframes When, i.e. Q=2, then the network equipment can select that the Q values are not sent into terminal clearly, and only need to be in descending sub frame #4 and descending Subframe #5 implies Q respectively according to above-mentioned method_#4=1 and Q_#5=1, i.e., it is multiple in descending sub frame #4 and descending sub frame #5 difference A up assignment is sent out in one up assignment less, and terminal need to only update a frame structure when subframe #4 is received, and receive A frame structure is updated when to subframe #5 again.Certainly, the network equipment can also be in descending sub frame #4 or descending Frame #5 directly implies Q respectively according to above-mentioned method_#4=2 or Q_#5=2.

Because each descending sub frame is likely to the information changed with sub-frame property temporarily, therefore can also be in terminal One counter is set, first by the counter O reset, at the letter that the sub-frame property for receiving the network equipment each time is changed temporarily Breath (either explicit or implicit) after, Q values and up-downgoing change directional information are read, and the Q values are added to counter, than Such as, briefly, can by counter top bit be used for indicate that sub-frame property changes direction temporarily, if it is descending be changed to it is up, The then value increase Q of counter, if up be changed to descending, the value reduction Q of counter, until present sub-frame #t is special subframe, At this moment newest Q values need to be read from Counter Value, and directional information more new frame knot is changed according to the newest Q values and up-downgoing Structure, wherein, if corresponding to Q values being increased up assignment number, correspond to by least one subframe in current frame structure by Descending sub frame is changed to sub-frame of uplink, if corresponding to Q values being the up assignment number reduced, corresponds in current frame structure At least one subframe is changed to descending sub frame by sub-frame of uplink, while by counter O reset, next round counting is carried out, until next Individual special subframe.

Example IV

The request that sub-frame property is changed temporarily can also be initiated by terminal：Assuming that the frame structure uplink/downlink frames knot that terminal is current Structure is frame structure i (0≤i shown in Fig. 2<N), in the case of similar to scene one and scene two, terminal is sent to the network equipment Sub-frame property changes request temporarily.After the network equipment receives the request, according to the load of the network equipment, the business of terminal, terminal Position, one or more parameter in the disturbed condition of terminal and the channel quality of terminal changes or other situations To confirm to agree to or refuse this request, terminal is notified to face by way of such as embodiment one to three is discussed if agreeing to The sub-frame property of Shi Genggai one or more subframes, communicated if refusal also according to original frame structure.Terminal is only Have and corresponding sub-frame property is just changed when receiving the signaling changed temporarily, otherwise also led to also according to original frame structure Letter.

Certainly, terminal can tell the network equipment needs to change to work as with feedback message to the network equipment by feedback message The attribute of which subframe in preceding frame structure.

Embodiment five

It is different with various embodiments above, after the information that the network equipment issues that sub-frame property is changed temporarily, may be used also in flow To increase the link of terminal feedback acknowledgment, i.e., only both sides just update frame structure after the network equipment receives confirmation, in order to avoid terminal The information that the sub-frame property of the network equipment is changed temporarily is not properly received, so as to cause transmitting-receiving two-end downstream transmission to lose Match somebody with somebody.But typically do not recommend so to do, reason is that the reliability of the receptivity of general down control channel and RRC signaling is all non- Chang Gao, even if still further aspect is fed back using terminal, but equally also there is the network equipment to be not properly received terminal feedback Situation, can not thoroughly solve the problem.On the other hand, because the network equipment works in the full-duplex mode, therefore in terminal In the case of not feeding back, as long as the network equipment judges that terminal is not properly received the information that sub-frame property is changed temporarily, than Frame structure after such as being changed according to sub-frame property, the network equipment should be that the subframe that user equipment downlink receives detects the terminal Upstream signals, or the network equipment should be terminal uplink send subframe do not receive the up of any terminal Transmission energy, then the network equipment can be returned to original frame structure, and retransmit the information that the sub-frame property is changed temporarily.

Can be that each half-duplex terminals determine independent frame knot it is pointed out that more than in each embodiment Structure, and k values, t values, Q values, m values and L values.M value can not also be provided, so, ' interim ' change here is just into ' forever Change long ', until being connected to new interim change directive.In addition, usually, it is descending son that will not occur changing sub-frame of uplink simultaneously Frame and the situation that change descending sub frame is sub-frame of uplink.And the transmission of the control information such as up-downgoing assignment, confirmation is considered, one As also a whole frame will not be all changed into it is up or all be changed into descending.

It is pointed out that as long as the transmission side of the information of unified sub-frame property change is confirmed between the network equipment and terminal Formula, it can use between the realization rate of these sub-frame properties change discussed in embodiment one to five, terminal is receiving After these change directives, according to the ascending-descending subframes attribute after change communicate accordingly.
